Unusual problem this. I have 37pfl4007 latest firmware and latest version of ipad app. Have been unable to get the app to see the TV recently, so I downloaded the Android app on my phone, which does work. I have noticed that the ipad app can see the TV now but only when the Android app is connected as well. Close the Android app and the TV disappears from the ipad app and it just keeps searching until the Android app is reactivated.
